Yep. The problem here, is that AP to AP connectivity isn't in the 
802.11b spec. So trying to create a city wide mesh of a mismash of 
proprietary protocols would be a nightmare. The obvious solution is 
everyone using IBSS (adhoc) mode. Problem there is it's hard to get on 
the roof unless you run a lot of cable. There are some solutions, like 
soekris boards, mini itx boards, linksys wet11's, buffalo ethernet 
converters... all these will do IBSS and are compact enough to put up a 
pole...
